Adderall vs. Vyvanse

Are Adderall and Vyvanse the Same Thing?

Both Adderall and Vyvanse are a central nervous system stimulants. Each is a medicine prescribed to treat attention deficit hyperactivity disorder (ADHD).

Both drugs are derivatives of amphetamines. The difference between the drugs is Adderall contains amphetamine salts (amphetamine and dextroamphetamine), whereas Vyvanse contains lisdexamfetamine, which the body converts to dextroamphetamine before it is active, meaning it's a "prodrug."

The extra time the body takes to convert Vyvanse to dextroamphetamine tends to make the side effects less pronounced, but the side effects of each of these drugs are very similar. They included anxiety, sleeplessness, digestive issues and some other problems.

Both Vyvanse and Adderall are in the amphetamine family of drugs, which means they have the potential to cause addiction and withdrawal symptoms.
